Abstract: Birds constitute an important part of the earths’ vertebrate organisms and are among the most diverse, conspicuous and fascinating forms of life. There are over ten thousand species of birds in the world. Besides their great ecological role in seed dispersal, pollination, importance in food weds / chains, they have also been crucial to man for meat, communication, recreation, decoration and as a source of inspiration. Unfortunately about 1,012 species of birds are being threatened by extinction due to anthropogenic induced factors, (Tabur, 2006). A perception survey was done by carrying out a questionnaire interview of villagers to determine their appreciations of avifauna diversity, importance and conservation with an objective to determine conservation principles for birds in communal
areas. Avifauna diversity perceived by the community was confirmed by a scientific bird survey carried by the researcher. The bird listing technique was used to determine avifauna diversity and abundance. SSPS, excel, Sutrop salient index packages and ecological indices were applied to analyse the data obtained from the research. High appreciation of avifauna diversity and importance was revealed by the study among the communal people of Mupari. The use of Sutrop indicated that edible birds and those that pose little problems to crops and
domesticated animals scored higher salience. Birds that had higher Sutrop salience value also form one cluster when analysed by the Principal Component and Hierarchical Cluster analysis. The research revealed little access to information on birds from respective monitoring and enforcement institutions. Great avifauna diversity exists in this communal area and bird conservation institutes need to work with such communal areas locally and across the globe to preserve this genus in light of their great mobile characteristic.2018-01-01T00:00:00ZMwadzingeni, KangamwiroNematode parasites of the nile tilapia (Oreochromis niloticus, Linnaeus, 1758) and the sharptooth catfish (Clarias gariepinus, Burchell, 1822) in lower Umguza dam

Title: Nematode parasites of the nile tilapia (Oreochromis niloticus, Linnaeus, 1758) and the sharptooth catfish (Clarias gariepinus, Burchell, 1822) in lower Umguza dam

Abstract: The study sought to determine abundance and species of nematode parasites of Oreochromis tilapicus and Clarias gariepinus in Lower Umguza Dam,in the Gwayi catchment area. Fish samples were collected from fishermen and sent to the laboratory for observation and identification using standard parasitological methods and identification guides. 479 nematode parasites were recovered from 160 fish belonging to 2 species; Oreochromis tilapicus and Clarias gariepinus. Four nematode genera; Paracamallunus sp., Eustrongylides sp., Contracaecum sp., and some unidentified nematodes parasites were recovered. Of the 160 host fish samples collected, 78.1% had nematode infections. 43.8% of the nematode parasites recovered were from Nile tilapia and 56.2% from Sharp-tooth catfish. Parasite abundances differed significantly (P<0.05) between the different nematode genera recovered from both Oreochromis tilapicus and Clarias gariepinus. The most abundant nematodes were Paracamallunus sp. (48.6%). Eustrongylides sp. and Paracamallunus sp. contributed 18% and 33% respectively. Unidentified parasites constituted 0.4% of the total number of nematode parasites collected. The results revealed a positive correlation (r = 0.681) between fish size and nematode parasite loads. Nematode parasites between the two host species were significant (P<0.05). Parasite abundances between the different sampling sites were not statistically significant (P>0.05). The results of the study indicated that the general abundances and levels of infestation were low in Lower Umguza Dam and this could be attributed to the above normal rainfall that was received between December 2016 and February 2017. Further studies on comprehensive fish parasite groups are recommended as the study only looked at nematode parasites.2017-01-01T00:00:00ZTshuma, Busiso M.
